Of those 11 people, Szabo’s writings were found to have uncanny similarities to language used in the white paper. They found a number of distinct linguistic traits appearing in both the white paper and his blogs. For example, phrases like “trusted third parties” and “for our purposes” showed up repeatedly, as did the use of commas before “and” and “but” and the use of adverbs and pronouns.

The team said none of the other possible authors were anywhere near as good of a match.

This isn’t the first time that Szabo has been pegged as the author of the white paper. Last year, researcher Skye Grey came to the same conclusion but even still, it’s far from a smoking gun.

Szabo is a well known name in the cryptography community and is an expert in law, finance, cryptography and computer science. The researchers said they aren’t sure if he created Bitcoin but they think he probably wrote the paper so it’s certainly worth a closer look.
